Description:

Qtractor is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework. Target platform is Linux, where the Jack Audio Connection Kit (JACK) for audio and the Advanced Linux Sound Architecture (ALSA) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Features:

- Multi-track audio and MIDI sequencing and recording.
- Developed on the Qt C++ application and UI framework [1].
- Uses JACK [2] for audio and ALSA [3] sequencer for MIDI
as multimedia infrastructures.
- Traditional multi-track tape recorder control paradigm.
- Audio file formats support: OGG (via libvorbis [6]),
MP3 (via libmad [7], playback only), WAV, FLAC, AIFF
and many, many more (via libsndfile [4]).
- Standard MIDI files support (format 0 and 1).
- Non-destructive, non-linear editing.
- Unlimited number of tracks per session/project.
- Unlimited number of overlapping clips per track.
- XML encoded session/project description files (SDI).
- Point-and-click, multi-select, drag-and-drop interaction
(drag, move, drop, cut, copy, paste, paste-repeat, delete, split, merge).
- Unlimited undo/redo.
- Built-in mixer and monitor controls.
- Built-in connection patchbay control and persistence
(a-la QjackCtl [16]).
- LADSPA [5], DSSI [11], native VST [12] and LV2 [13] plug-ins support.
- Unlimited number of plug-ins per track or bus.
- Plug-in presets, programs and chunk/configurations support, including
native VST FXB/FXP file support.
- Unlimited audio/MIDI effect send/return inserts per track or bus.
- Loop-recording/takes.
- Audio/MIDI clip fade-in/out, cross-fade (linear, quadratic, cubic).
- Audio/MIDI clip gain/volume, normalize, export.
- Audio/MIDI track and plugin parameter automation (dynamic curves,
sample&hold, linear and spline modes).
- Audio clip time-stretching (WSOLA-like or via librubberband [9]),
pitch-shifting (via librubberband [9]) and seamless sample-rate
conversion (via libsamplerate [8]).
- Audio/MIDI track export (mix-down, render, merge, freeze).
- Audio/MIDI metronome bar/beat clicks.
- Unlimited tempo/time-signature map.
- Unlimited location/bar markers.
- MIDI clip editor (matrix/piano roll).
- MIDI instrument definitions (a-la Cakewalk(tm) (*.ins) [18]);
SoundFont (*.sf2) and MIDI Names XML (*.midnam) files also supported.
- MIDI controller mapping/learn/assignment (mixer and plug-in parameters).
- MIDI system exclusive (SysEx) setups.
- JACK transport sync master/slave.
- JACK session support.
- NSM (Non Session Management) support [15].
- MMC control surface enabled.
- MIDI Clock, Song Position Pointer (SPP) support.
- Configurable PC-keyboard and MIDI controller shortcuts.

Last changelog:

0.9.3 2018-12-07 The End of Autumn'18 release 12 days ago

- Auto-backward now skips the end-of-session location.
- Audio clip time-stretching and pitch-shifting limits are now 10-fold in either direction.
- Custom color (palette) theme editor introduced; color (palette) theme changes are now effective immediately, except on default.
- Old deprecated Qt4 build support is no more.
- Recover audio and MIDI dedicated port connections when changing any of the Metronome, Player and/or Control option settings.
- Fix MIDI track (and bus) bank/program reset to none.
- Anti-glitch micro-fade-in is disabled on audio clips with zero offset.
- Audio and MIDI file players also stopped on Transport / Panic command.
- LV2 plug-in UI GTK2 and X11 in Qt5 host native support are now disabled on default configure.
- Get rid of symlink duplicates on the default plugin search paths.
- According to Debian policy and guidelines, the out-of process plugin scanner (qtractor_plugin_scan) is now installed to $LIBDIR/qtractor.

> ./configure --with-qt=/usr/share/qt4

Of course in case of qtractor, where nobody is calling qmake manually, this works, too. Configure then behaves just like with QTDIR=/usr/share/qt4 exported and make will call the *-qt4 executables. Not so different from your distro, is it?

Anyway, despite of the somewhat stressful attitude in this thread, qtractor looks nice.

0.9.2 2018-09-09 Summer'18 release 3 months ago

- AppData/AppStream metadata is now settled under an all permisssive license (FSFAP); also updated to be the most compliant with latest freedesktop.org specification and recommendation.
- Fix build for Qt >= 5.11.0 (by David Geiger, thanks); also for some g++ >= 8.1.1 warnings and quietness.

0.9.1 2018-05-29 Pre-LAC2018 Release Frenzy 6 months ago

- Extended multi-selection is now supported on all the Connections client/port lists, allowing for multiple (dis)connections at once.
- Added LV2 UI sample-rate option support.
- Always reset all internal dedicated MIDI controllers, eg. MIDI track volume (CC#7) and panning (CC#10), on Transport/Panic and after rendering export to aud1io (ie. Track/Export Tracks/Audio...) as needed to reset MIDI instrument plugins to nominal session state.
- Fix, detect and preserve MIDI Bank-select method across MIDI track/clips editing operations.
- Fixed MIDI track and clip note min/max display range while recording and also when duplicating tracks.
- Added "All files (*.*)" filter to every file requestor dialog, wherever missing.
